Do you already have one of Holley's Terminator EFI Systems and want to add a second throttle body for a twin 4-BBL setup? We've made it easy!
You can take your pick of any of the five different color/style combinations (including the standard silver and gray throttle bodies) and couple this with your existing Terminator kit to have everything you need. Bolt this onto your 2x4 intake manifold, add the linkage and air cleaners, plumb the fuel and configure according to included instructions. And, as with all of our kits and systems, you get personalized technical support from our in-house Holley-trained Tier III technician.
This kit includes:
- Slave Terminator throttle body with injectors
- Fuel Line Assemblies (for Stealth throttle bodies only)
- New Terminator 2x4 Main Harness
- Terminator 2x4 Injector Harness
- Base and air filter gaskets
The Twin Terminator system is built to order and, as such, special order terms apply. Please reference our Terms & Conditions for Special Orders.
Or Maybe You're Starting From Scratch
Did you arrive here looking to build a complete dual-quad throttle body EFI system from the ground up? In that case, save time, money, and frustration by purchasing our complete Twin Terminator Dual Quad Throttle Body Kit! We've eliminated all of the guesswork. Your system will arrive completely configured and ready to install and start.
Note: Holley Terminator EFI Systems with twin throttle bodies benefit from dyno tuning. Be sure to purchase the optional USB cable if you don't have one already. You can download the laptop tuning software here. Also, clearance and linkage are always issues of concern on a twin throttle body setup. We're happy to provide whatever measurements you need in advance of your purchase so you can ensure fitment. In virtually all cases Stealth throttle bodies must be mounts with the fuel tanks to the sides of the engine.
